Step 6: On the upper right side of the main circle, draw two triangles as guides for Tom's ears. Draw the ear on the left bigger because of the perspective.

Step 7: That's it for the initial sketch! You have the basic Tom shape, so now go in and tighten your drawing. From this point on, press harder with your pencil in order to get darker lines and a more defined sketch.

Step 8: Darken Tom's nose using the initial shape as a guide. Make it more round on the sides. Draw the top part of Tom's mouth using a series of bumps on top that follow the horizontal construction line, and then draw two bigger bumps under his nose.

Step 9: Draw a curved line on the left side of the mouth for Tom's cheek. Draw two long lines on either side of this cartoon cat's mouth for his whiskers.

Step 10: Use the initial U-shape as a guide to draw the mouth and make it bend more. Inside Tom's mouth, draw two bumps for the tongue.
